Case:
The Seagate 320GB hard disk of Fuyong customers can normalize disk information normally, but the disk management can only recognize the C area, and it cannot be opened. The access speed is very slow.
Solution:
According to the customer’s description, the preliminary determination is a bad channel. The use of professional data recovery equipment is further tested. It is found that the No. 1 magnetic head of the hard disk is not good. It cannot read the hard disk data. The magnetic head needs to be replaced.After the magnetic head is replaced in the dustless room, the No. 1 magnetic head can be accessed to the plate, but the plate still has a relatively serious defect. The mirror processing of No. 1 magnetic head is processed, and the final data recovery rate is 100%.
